Application filed May 5,

To all whom it may concern:

Be it known that l, PHILIP J. MEAHL, a. citizen of the United States, and a resident of the city of Summit, in the county of.

5 Union and State of New Jersey haVeinvented an Improvement: in Music RolL Printing Machines of which the following is a specification.-

This invention relates to improvements in 15 characters-on a music sheet, andwhich has the characters removable r ad ustable on a,

moving part of the machine. Other objects of the invention will be apparent from the following; detailed description.

In the printing art especially. as 'app lied to. operations in connectlon with lacing? characters on music sheets which are used on automatic or semi-automatic musical. in'strii ments, has been exceptionally difiicultQto. place such characters atreq'uired saians; especially where characters whiehfincllide words or. syllablesmustbe placed l" i with certainperforationsin thelmusic sh t.. Heretofore such characters have beenfpIacedQ by, forming apattern of, paper with characters forced or raisedlffrom, the surface. of the pattern which is then brougheina; contact with the music'sheet. This meta is undesirable as it necessitates a new sheet: or pattern for each song. andtheQr-ais'ed; characters soonbecomejw'orn' anddes troyedij One of the objects of this invention'fis to, provide a means for bringing into contact. with the music sheet type which'isladjiistj-i able as to position and which permits print-fv ing ofa great number of music sheets without wearing; i

Referring now to Figure 1 in the drawings. the machine 1 has frame 2, carrying aswheel 3 which receives a. conveyer A. idle, wheel 5 is mounted on frame 6 andalso.Ire-1 ceives the conveyerand is adjustable po-[ sition to vary the tension athe conveyer. A music sheet 7 isv drawn from the supply rack 8 and is carriedby impression roller. 9 mounted in theyframeQlO which ispivotallymounted at 11. v presser' roller 12 mounted on the frame 2 and biased .inposi 13. The music sheet moves" between thetwo rollers and has a linear speed equal to that of the conveyer so'that the music sheetnia'y. be brought into contact with the typesets' carried on the conveyer. A. weight .14; is: pivoted at 15 on the supply rack and con: tacts with the music sheetlto hold it tau t be-- tween the rack and the impression rollerfl A rack 16- receives the music sheetafter it passes beyond the presser roller. Rollers-17 on the rack 16 are provided with. short belts 18 preferably madeof canvas and. may be-driven at various speeds, generally atia little higher rate than the speed 1 of the music, sheet so that there will be tendencyto pull the music sheet fromthe printing. machine. It is preferable, however, to have. the belts farthest away from the, printin machine moving-at a greater rate of spec than'the belts nearer. I I j tin-5 mitted through chains. and idle pulleys are employed so that there will be 0 lost motion when the machine stops.

The conveyor which carries the type sets may be of any suitable tlorm or material and is herein shown as being made of such suitable material that is substantially nonextensible. The longitudinal strains in the conveyer are low as the resistance to the movement of the eonveyer during the operation oi? the machine is very small. The characters to he printed are preferably formed. on a bar 25 which has the type s'yllableor letter 26 formed thereon. These characters may be of one or more letters or figures. This bar with the characters thereon, tor the purposes o'l description and reference in the claims will hereinafter be referred to as a type .et or type units. Mez'ins are provided to hold the type sets on the conveyer such as holders 2'? which are held. in position by rivets 28. The ends of the holders are turned back on themselves as illustrated at 29 and 30, and the extreme edges are corrugated at 31 to receive the type sets. The two ends oil the type set are cut down and slotted at 32 so that the ends thereof may be properly adjusted and held in the holders 2?. Referrmg particularly to figure 8, there is disclosed a holder with type set properly placed therein and the section of the type set as shown in figure 9 taken. with the disclosure in figure clearly illustrates one the type sets and the method of positioning it in the holders. in preparin g' the conveyer for use in the machine. the position of the perforations and the words or characters which are to he placed opposite certain perforations. are carefully noted and the type sets placed in the holders so that the conveyor as it moves in synchronism with the music sheet carries the characters or words into printing. relation with the music sheet and opposite the proper perforations.

.During operation the conveyer contacts with the outer surface of wheel 3 so that openings 33 in the conveyer receive teeth 3&- which are mounted on the wheel and a positive drive o'lthe conveyor results. Mounted on the shaft of the impression roller is aring'35 which contacts with the conveyor.

The impression roller itself, which carries the music sheet, is adjustable relativelyto ring 35. This adjustment provides for e positioningthe impression roller 1n respect to the height of the type. Knob when t pushed inwardly operates a clutch so that he impr ion roller proper may be rotated irrespective of the chain drive mechanism. The impression roller-and ring may be adjusted in the frame by means of set screws 37 2 and This adjustment provides for the position of the impression roller when conveyors are of rarious thicknesses.

in operating the machine, av predetermined mark on the music sheet is brought in contact with the presser roller and the impression roller is oscillated to normal op erating position. 'llhe brake on the wheel 3 is removed by p essingthe toot lever 35), and the pulley 21 of motor 19 is moved into contact with the wheel fl by pressing the foot lever "0 thereby driving; the wheel 3 which posi. vely moves the conveyer belt. The motion :liron'i the toot pedal 39 is transmitted; through av link 39 to a lever 4&0. one end or wh ch engages a collar Q1 mounted on a rod 4 This rod normally pushed dovuiwardly by a spring 43, which is connected at the common pivot point of a MW. 44%. \.l' top le is at one end 15 p: olcd to the the ot er end 4-6 to a lever 47. The latter lever is pivoted at 41-8 to the brake shoe 4'? afiid. at 49 to the frame of the machine. is normally held in an upward position with the spring l3 compressed and 1e rodan the shoe 4' withdrawn from the wheel 3 by the engagement ot a lock 50 which is pivoted to the lower end of the trip 44, and engages beneath the collar 41. The spring 51 tends to maintain the lock 50 in enp'agei..ent with the collar ll. but its action is destroyed by the movement of the trip A- which releases the lock 50 and permits the down *ard movement oi the rod 412 and the operation of the brake shoe. A link 52 is coun ted to the hase of the motor 19, is slidahly connected by slot-and-pin engagement 53 with the tramc oi the machine. and is i'iormally held in its uppermost posi t on so that the pulley 21 on the armature shaft of the motor is held in ei'ig'agement with the wheel The weight 45 operaton the link moves the motor 19 about pivot 20 and disengages the pulley 21 the wheel 3 when the trip 42 is disenrom the upper end of the link 52. s also transmitted throu 'h the repears and the chain drives to the impression. roller and to the inking rollers. The reduction gears are adjusted sd that the speed 0'" the i pression roller is in synchronism with the speed of the conveyor. and the music sheet is carried into contact with the type sets so that charactersare printed opposite proper perforations or at proper and 38 as noted in Figures characters have been printed on the music sheet the machine is brought to a stop and the impression roller oscillated to a remote position from the conveyer.

In bringingthe machine to rest the trips 41 mounted on the conveyer are brought into contact with catches 42, 43, and 44 successively and these catches release respectively the motor from the driving wheel by the dropping of weight 45; releases the weight 46 which oscillates the impression roller; and releases a brake catch which allows brake 47 to move against wheel 3 so that the conveyer is stopped in a predetermined position in order that it may,,upon starting the next time, print the characters in the proper places on the next music sheet. The trips 41 have lugs 48 which extend through openings 49 in the conveyer so that the lugs will contact with the catches which are adapted to extend through openings. A presser bar 50, being part of the frame 2, is positioned to force the lugs through the conveyers and to maintain them in contact with the catches. The three catches may be placed at any desired position on the frames and the positioning of the trips on the conveyer will operate the catches at predetermined intervals. It is to be understood that one trip may be substituted for a plurality of trips and in such a case the positioning of the catches on the frame of the machine will determine the intervals at Which the trip will properly operate the catches. It is, however, to be understood that this may have three separate catches for the operation of the various mechanisms of this machine or they may be combined in one so that it may perform the various functions. 7

It will b understood that the embodiment of the invention herein described and shown in the accompanying drawings may be vai'iously modified, and that the present invention is susceptible of different embodiments. In so far as such modifications and embodiments of the invention come Within the scope of the following claims they are considered to be within the scope of the invention.
